with \(\eta =\eta _{\chi }=\eta _{\phi }\) . We point also that, owing to the
existence of strongly relevant mixed term between two different Ising
fluctuating fields, the supersymmetry scaling relation \(1/\nu =(D-\eta )/2\) 
in the chiral Ising GNY model not holds exactly at criticality[1]}. In general
case for \(N_{f}\ge 1/4\) , the critical exponents define a new universality
class termed chiral Ising\(\times \) Ising universality class. To obtain the
estimate for the critical exponents at the physical dimensions \(\epsilon =1\) , we employ simple Pade approximant[2]}. At one-loop order, the Pade
approximant provides only [0/1] extrapolation for the exponents, our
estimates for different \(N_{f}\)  are listed in the Table. REF .
For \(N_{f}=1\) , the theory describes the quantum criticality of spinless electrons from semimetallic state to
insulating state which break sublattice or \(Z_2\)  symmetry, i.e., CDW phase. The \(N_{f}=2\)  GNY model describes the similar transition of spinful fermions on the honeycomb lattice.
